2014-14336. Airworthiness Directives; Dornier Luftfahrt GmbH Airplanes

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding airworthiness directive (AD) 2006-11-19 for Dornier Luftfahrt GmbH Model Dornier 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as chafed or damaged wiring on the flight deck overhead panels (5VE and 6VE). We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective July 28, 2014.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of July 28, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to Dornier Luftfahrt GmbH Model DORNIER LUFTFAHRT GmbH Models Dornier 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes. The NPRM was published in the Federal Register on December 23, 2013 (78 FR 77380), and proposed to supersede AD 2006-11-19, Amendment 39-14624 (71 FR 32268; June 5, 2006).

Since we issued AD 2006-11-19, Amendment 39-14624 (71 FR 32268; June 5, 2006), DORNIER LUFTFAHRT GmbH changed the compliance time between repetitive inspections and incorporated those inspections into the Time Limits/Maintenance Checks Manual (TLMCM).

The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states that:

RUAG Aerospace Services GmbH issued Time Limits/Maintenance Checks Manual (TLMCM) TM-TLMCM-090305-ALL, Revision 5 dated 20 March 2011 respectively TM-TLMCM-228-00002-150610, Revision 1 dated 03 March 2011, listing component life limits and describing maintenance instructions for the Dornier 228 type design. The Document TM-TLMCM-228-00002-150610 is valid for airplane SN 8300 and up and other airplane SN modified according to CN-228-247. The instructions contained in that manual have been identified as mandatory actions for continued airworthiness.

In 2005, chafed wiring was found on 5VE Panel due to lost adhesive of the TY-RAP holder and subsequent vibration of the cable harness.

To address this potential unsafe condition, RUAG issued All Operators Telefax (AOT) No. AOT-228-24-028 and Temporary Revision (TR) 05-05 of the TLMCM introducing repetitive of the cockpit overhead panels 5VE and 6VE and, depending on findings, corrective actions(s). Subsequently, LBA issued AD D-2005-438 (EASA approval 2005-6430) to require those actions.

Since that AD was issued, the instructions of TR 05-05 have been incorporated into TM-TLMCM-090305-ALL, Revision 5 dated 20 March 2011 respectively into TM-TLMCM-228-00002-150610, Revision 1 dated 03 March 2011.

For the reasons described above, this AD retains the requirements of EASA AD D-2005-438, which is superseded, and requires the implementation of the life limits and maintenance actions as specified in the TLMCM (TM-TLMCM-090305-ALL respectively TM-TLMCM-228-00002-150610) for zone 321 overhead panels 5VE/6VE.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/​#!documentDetail;​D=​FAA-2013-1056-0002.

After the NPRM was issued, we identified that we inadvertently omitted the calendar time compliance for the inspections of the wiring in the flight deck overhead panels. We issued a supplemental notice of proposed rulemaking (SNPRM) to propose adding the calendar time compliance for the inspections of the wiring in the flight deck overhead panels. The SNPRM was published in the Federal Register on March 4, 2014 (79 FR 12131).

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM (79 FR 12131, March 4, 2014) or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the SNPRM (79 FR 12131, March 4, 2014) for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the SNPRM (79 FR 12131, March 4, 2014).

Costs of Compliance

We estimate that this AD will affect 17 products of U.S. registry. We also estimate that it will take about 2 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $2,890 or $170 per product.

In addition, we estimate that any necessary follow-on actions would take about 3 work-hours and require parts costing $1,000, for a cost of $1,255 per product. We have no way of determining the number of products that may need these actions.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. “Subtitle VII: Aviation Programs,” describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in “Subtitle VII, Part A, Subpart III, Section 44701: General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this AD:

(1) Is not a “significant regulatory action” under Executive Order 12866,

(2) Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska, and

(4) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
